I was filling a bug report about that wget and curl wasn't working with HTTPS at all and trying to prepare console outputs to paste into this bug report. Then I just realized that in fact it was a problem with Turkish locale that I use with my home user.

$ locale

@Pierre: is this a ca-certificates issue as it is not specific to wget or curl?
Comment by Pierre Schmitz (Pierre) - Wednesday, 10 November 2010, 11:48 GMT
I was able to reproduce it with curl and wget. Doing a little strace revealed:

on tr /etc/ssl/certs/a9535edf.0 is opened which does not exist
on other locales /etc/ssl/certs/ae8153b9.0 is opened

@Pierre: with the?

I've already ran update-ca-certificates --fresh a few times. It doesn't seem to solve the problem.

This might be related with the classical case conversion problem of Turkish language:

ı -> I
i -> İ

But I'm not sure if the problem is related with this or not.

Sorry, ignore that last sentence; somehow missed to delete it (did it now). Yes, update-ca-certificates does not work. I have to say that I am not sure where the bug might be located.

Long shot... have you tried to rebuild wget?
Comment by Alper Kanat (T-u-N-i-X) - Wednesday, 17 November 2010, 18:18 GMT
I guess I haven't.. (if i remember correctly, i tried recompiling from aur but something went wrong and the package was orphaned afaik)
Comment by Allan McRae (Allan) - Friday, 03 December 2010, 14:13 GMT
Unassigning me as this does not appear to be a wget issue but rather somewhere down the dependency chain...
Comment by Timothy Redaelli (tredaelli) - Friday, 03 December 2010, 20:35 GMT
It's a multi-byte problem or something similar.

A good workaround, for now, can be to put "export LC_CTYPE=C" in ~/.bashrc

This boils down to out of date and/or missing ca-certs. curl includes a perl script (lib/ which downloads and converts a whole bunch of mozilla certs to a ca-bundle.crt file. Pointing wget or curl at this file via their respective ca-cert options fixes this bug. Not the ideal solution, so I kept digging...

Found this in OpenSuSe factory:

And this from Fedora Rawhide:

I've yet to test the sources they pull, but either one has far newer sources than our 2009 ca-cert package taken from debian. I'll look into this tomorrow. Also, as a note to myself or anyone else who pokes around at this, we should be careful that we don't conflict with 21719... or maybe the newer cert bundle will just fix it in the process.

edit: uhh, ignore the attached log files i was going to initially include but aren't necessary (and can't delete).

Attached are revised PKGBUILDs for wget and curl so that they point at the .crt bundle included with our ca-certificates package. We should deal with getting a new source for ca-certificates separately. Note that I've forced ca-certificates as a hard depend instead of an optdepend of wget.
